First of all, apologies, as I dare-say this has been discussed-to-death in other posts. However, as my NL is a bit slecht, I need your help in English...

We're about to move house. In the currently house I have the Electrabel Car-Plug, which was necessary to get around the problems of the UMC not working for many Belgian installations (why the **** hasn't Tesla addressed this???).

In the new house I will have a garage (woot!!), but of course when I tried the UMC I get 4 flashing red lights, so something has to be done...

Now this is a rented house, so I have to be careful with drilling and adapting too much, but the owner got a quote from the builders that renovated the place to install 400V 3Phase 16A with a red-socket in the garage for €2200 - seems a bit pricey to me.

My other option is to de-install my existing Car-Plug and wire that in - I guess this could be done fairly easily by just replacing one of the existing power sockets in the garage.

But, I realise that many of you have been through all this and I'd look for your advice...

Hi Dave,
As the grid is 3x400+N (re the quote for the red plug),
My first guess is that you only need to switch the two life wires in the socket in the garage, to make the TeslaUMC work.

But that will be slow charging @ 13km/h.
If you can use the red one, charging will be @50km/h.
Now 2200 € looks very, very, very expensive.

Can you take some pictures of the electrical cabinet, that will help us to assess.

Did you get the list of the things they are going to do for this €2200 pricetag? I installed a red CEE socket at 3 locations myself but the circuits were already wired for 3F+N so it was pretty easy.

The house has recently been renovated you say. Then all sockets should have proper earth. You can double check.

The cheapest solution will be moving your existing CarPlay charger. You already own it, and it's easy to move. If you do not mind the slow charging.

2200 Euro for a 3-fase 400V is way overpriced. A socket costs no more then 15 Euro, the breaker like 20 Euro and then add some wiring and labor. Unless of course the house does not have a 3-fase connection. Adding 3-fase to a house will cost about 2000 Euro.

Did you try to rotate the schuko plug 180 degrees? ( is this the same as using the FR adapter?).

In my house I had a lot of trouble due to weak grounding. It seems difficult to figure this problem out.
but the sollution was actually nog very expensive, one grounding pin was all that was needed. (300 incl installation).

A Juice Booster will be more expensive than your current already owned CarPlay charger, but will be portable to anywhere else you move or travel to. A second version is due out soon, so depending on your rush, perhaps you may want to wait for that, even if only for the fact that the first versions may drop in price when the new one hits the market.

That Juice Booster looks like an interesting product, but the website doesn't describe too well what it does (other than replacing UMC). Is it the case that you can plug it into any source and in theory it will sort it all out and "just work"?

I'm not sure I am following you here... Why third party? The blue UMC adapter from Tesla will allow charging at 32 km/h with single phase 32A.

Dave, do you have 32A or more on your main switch in the circuit braker?

Hi slcuervo - I don't know, I've not yet got access to the house, I just went previously on arrangement with the owner - the house is rented, so this also limits what I can/can't do. I get the impression that it's 16A...

Or perhaps I could just get hold of a Norwegian UMC adaptor - will certainly be cheaper than other 3rd-party cables, no?

Based on the quotation, my estimation is that the grid in the new house is 3x230v. Most important about that : without neutral.

The TeslaUMC, as used in the EU, whether on schuko, blue or red socket always require the neutral.
So it will not work !

Third party UMC's, like Juicebooster, Ratio, Mennekes or home-made, do not require the neutral. Same for the TeslaUMC as used in Norway only.
So with any of those, you should be able to charge mono phase, up to 32A. Equals approximately 32km/h.

Now, you do have the Electrabel Charger. I am not familiar with this one, but I know about other Tesla Owners who are also on the 3x230V grid, and use the Elevtrabel-charger at home.

So imho, you already have the necessary equipment, we only need a 'connaisseur' to have look.
Maybe the guy who installed the Electrabel-charger in the first place.

To be complete, but make things even more complicated, there are 3x230V grids where you still can use the TeslaUMC... But before I can tell this is the case, I would need a picture of the incoming cable, or a reading on a ordinary multimeter.
